What is a Bomb? Bombs are explosive devises. They can be constructed to look like almost anything and can be placed or delivered in any number of ways. (How we wish they all looked like the ones shown in movies, with fancy switches, colourful wires and a big watch hanging with the whole paraphernalia!)The only common denominator that exists among bombs is that they are designed to explode.
Treat all threat calls as important. Just because statistics suggest that most of the bomb-threats are hoax, it does give us any room for complacency.
